我厂的铅烧结焙烧,自1955年起就采用了D-L带式吸风烧结机。多年的生产实践证明,这种烧结机的生产能力、机械化水平虽比较高,但还有很多缺点,如废气中SO_2浓度很低,平均为0.8%,经收尘后放入空气,每年放空损失的硫量达7000～8000吨,不但给SO_2的回收利用造成困难,而且污染了大气;经常发生粘结炉篦、堵塞吸风箱等故障,特别是处理含铅大于45%的炉料时更加困难,甚至使作业无法进行,须经常清理炉篦和吸风箱,且炉篦、烟道等经常
Lead sintering plant roasting, since 1955 has adopted the D-L belt suction sintering machine. Years of production practice has proved that this sintering machine production capacity, although the mechanization level is relatively high, but there are many shortcomings, such as low concentrations of SO2 in the exhaust gas, an average of 0.8%, after the dust into the air, the annual vent loss Of sulfur up to 7000-8000 tons, not only for the recovery of SO_2 cause difficulties, but also polluted the atmosphere; often bonded grate, block suction bellows and other failures, especially when dealing with more than 45% lead content more difficult, Even the operation can not be carried out, the grate and the suction box must be cleaned regularly, and the grate, flue and the like often
